Trump Focused on Kavanaugh, Kethledge for SCOTUS, Source Says Brett Kavanaugh and Raymond Kethledge are both conservative federal appeals court judges. Kavanaugh serves on the U.S. Court of Appeals for the District of Columbia Circuit. Kethledge serves on the Cincinnati-based 6th U.S. Circuit Court of Appeals. Both are in their early 50's. They could potentially serve decades in the lifetime post on the nine-member court. The source told Reuters that Amy Coney Barrett of Indiana was still in contention. President Trump, however, had been asking more questions about Kavanaugh and Kethledge.
